ATTROPEN(3C) Standard C Library Functions ATTROPEN(3C)
attropen - open a file
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
int attropen(const char *path, const char *attrpath, int oflag,
/* mode_t mode */...);
The attropen() function is similar to the open(2) function except
that it takes a second path argument, attrpath, that identifies an
extended attribute file associated with the first path argument. This
function returns a file descriptor for the extended attribute rather
than the file named by the initial argument.
The O_XATTR flag is set by default for attropen() and the attrpath
argument is always interpreted as a reference to an extended
attribute. Extended attributes must be referenced with a relative
path; providing an absolute path results in a normal file reference.
Refer to open(2).
